Abstract

1. Precision boring tool for making precision bored holes comprising a cutter head having arranged on its circumference several cutter bars, each being pressable by a securing device against a shoulder of said cutter head, the distance of said cutter bars from the longitudinal axis of said cutter head being different and said cutter being offset from one another in the direction of said longitudinal axis, characterised in that three cutter bars (1, 2, 3) of circular design are arranged at a spacing of 120 degrees on the circumference of said cutter head and are offset in the axial direction such that the effective cutting edge sections of said cutter bars (1, 2, 3) continually pass over into one another when projected onto a plane of the axis.
